STRAIG HT- WAY VALVE.

SPECIFICATION forming part of Letters Patent No. 450,588, dated April 14, 1891.

Application filed November 13, 1890. Serial No. 371,305. (No model.) I

To ctZZ whom, it may concern:

Be it known that I, EDMUND LUNKEN- I-IEIMER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Straight-Vay Valves,of which the following isa description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to what may be called oscillating valves, for the reason that the passage between the pipe-connections, arranged 1n line with each other, is closed and opened by a pair of valve-disks operated by an oscillating or rocking spindle or valvestem which swings them into and out of line with the pipe-connections. The rocking spindle is journaled in bearings parallel with the line of the pipe -connections, and the valve-disks move at right angles to such line. IVhen swung into line with the connections to close the valve, they fit snugly against seats at the inner sides of said connections, all as'shown and described in a number of patents heretofore granted to me, the last of which is No. 426,539, of April 29, 1890.

My present invention consists in certain improvements in the frictional bearing for the spindle, and in a novel method of supporting one of the valve-disks, all as will be herein set forth, and specificallypointe'd out in the claims.

In the accompanying drawings, Figure 1 is a plan View of the valve. Fig. 2 is atop view of the valve-shell shown in Fig. 1 with the cap removed. Fig. 3 is a vertical section on the dotted line 3 3 in Fig. 1, looking in the direction of the arrow at right angles to said line. Fig. I is a vertical section on the line 4: tin Fig. 1,1ooking in the direction of the arrow at right angles to said line. Fig. 5 is a perspective view of the two valvedisks. Fig. 6 represents details of the spindle-opening in the valve-shell and the friction-ring adapted to fit therein. Fig. 7 is a perspective view of the spindle.

The same letters of reference are used to indicate identical parts in all the figures.

The valve-shell, with the exception of the cap, is cast in one piece, and consists of the chamber A, pipe-connections B B, and tubular portion C. The pipe-connections are in line with each other, as is usual in this style of valves, and are interiorly threaded to receive the pipes. The open ends of the valve- 5 5 shell body, through which the disks are in serted, is closed by a cap D, bolted to the body of the shell.

The valve-disks E E are two in number, and adapted to fit and be forced against inclined seats F F in the body of the shell. The lower disk E has at one side an integral carrier E by which it is supported upon the rocking spindle G, the lower rectangular end of the latter passing through a similar-shaped 6 5 opening in the disk-carrier, so that the rocking or oscillating movements of the spindle will be communicated to the valve-disk to swing it into and out of line with the pipeeonnections to close and open the valve. The lower end of the spindle restsupon the shell at the bottom of the tubular portion C, and is provided with a pin fitting a seat in the shell to hold the spindle true in its bearings.

The upper disk E is not supported by the spindle as is the lower one, but is supported entirely by the lower disk itself. There is a bearing H between the two disks at their centers, and on its side next the spindle the upper disk is provided with a pendent pin I, concentric to said disk and extending loosely through a hole in the carrier E of the lower disk. The central bearing H and loose eccentric connection by the pin I allow the disks sufficient play relatively to each other to permit them to properly adjust themselves to the inclined seats F F when the valve is closed. At a point oppositeor nearly opposite the pin I the upper disk is provided on its under side with a lug J, which fits loosely between two c lugs K K on the upper side of the lower disk. The purpose of this connection of the two disks by the lugsJ K K is to preventthe upper disk becoming displaced from its proper position on the lower disk when the valve is g 5 opened or closed.

The valve-spindle G is provided with an integral friction-collar L, having a beveled upper side. Fitting snugly around the cylin drieal portion of the spindle above the fric- I00 tion-collar is ascrcw-plug ll, screwed into the spindle-opening in the shell and affording the upper bearing for the spindle. Surrounding j the spindle immediately above the collar L, I the two bearing-surfaces being preferably 1 ground, is a ring N, Fig. U. This ring has ears upon its opposite sides, which lit within grooves in the sides of the opening Fig. t3, and prevent the ring turning. Between the ring and the lower side of the screw-plug M is interposed suitable packing 0.

By tightening up the screw-plug; M the triotion-ring N may be made to bear against the collar L and likewise the bottom of the spindle against the shell with any desired degree of pressure, so that greater or less resistance may be offered to the turning of the spindle. \Vhen the spindle is turned by the handle P applied to its upper end to open the valve to anydegree desired, the disks will remain at that point when the handle is released and will be held there against ordinary shocks or jars.

The non-revoluble ring N prevents the movements of the collar i. and spindle from being" communicated to and loosening the plug M. It will of course be understoodthat said ring may be held from turning by other means than by the ears on it and the grooves in the spindle-opening.

As before stated, the connection of the disks E E by the lugs J K K is only for the purpose of preventing displacement of the upper disk and may be dispensed with where other means are employed for the purpose. Thus in another application tiled simultaneously with this and bearing serial number 371,306,l have shown a rectangular lup; and hole substituted for the round pin I and the round hole in the carrier E, which renders the 0011- 3 nection above referred to unnecessary.

My present invention has certain advanl tages over the constructions shown by the i patents heretofore issued to me. in my pati cut No. 354,019 only one ralve-seat and one valve are shown and the valve-seat is not an inclined one. Theconnection of the valve with its carrier by means of the flanges outside of the valve did not hold the latter positively in place so that it was non-revoluble, as is the disk E of this case, and which by its positive eccentric connection with the disk E is constantly held in one position relative thereto; but the greatest advantage resulting from the present construction over that shown by the said patentis in the greater symmetry, chcapness, and rompactness, as the tlang'es outside of the valve-disk of the said patent, and by which said valve-disk is held in place on its carrier, require a valve-shell ot' a diameter materially greater than is required for my improved valve. In the valve shown by my patent No. @6539 the valvedisks both have connections with their oscillating spindle and one is not supported by the other, as in the present case, this new con-' i E, supported by the disk E and co-operating with the inclined seat F, a central bearing H between the two disks, and an eccentric connection between said disks by the pin Ion one and a correspondinghole in the other for positively preventing displacement of the disk E,-substantially as described.

12. In a valve such as described, the combination of the shell having the two inclined seats F F, the rocking spindle G, parallel with the line of the pipe-connections, the valve-disk E, supported on said spindle by its integral carrier E and co-operating with the inclined seat i the non-revoluble disk E, supported by the disk E and co-operating with the inclined seat F, a central bearing H between the two disks, an eccentric connection between the disks by the pin 1 on one 1 and corresponding hole in the other, and a second eccentric connection between them, as by the lugs J K K, substantially as described.

l. In a valve such as described,the combination of the shell, the rocking spindle G, provided with the friction-collar L, the nonrevoluble friction-ring N, bearing upon said collar, the screw-plug M, and the packing O,

f interposed between the plug M and the ring N, substantially as and for the purpose described.
